YARN CLEANER.

Application filed January 3, 1924;. Serial No. 6%,132.

To all ctr/eons it may concern:

Be'it known that I, LOUIS B. HASBROUOK,

acitizen of the United States, residing at Elmira. in the county of Chemung and State I of New York, have invented certain new and useful Improvements in Yarn Cleaners, fully described and represented in the following specification and the accompanying drawing, forming a part of the same.

This invention relates to yarn cleaners and aims to provide a simple and effective device for removing impurities of all sorts from a traveling yarn. An object of the nvention is to provide a yarn cleaner in which all impurities removed from the yarn and any fibrous matter detached with them are continuously discharged from the cleaner without the use of any mechanically driven parts. A. further object of the inventlon is to provide a yarn cleaner wh1cl1 w1ll place the yarn under any desired tension so that no tension device need be used in the cleaner. A still further object is to provide a cleaner which will automatically adjust itself for operation upon a yarn of any s1ze.

A yarn cleaner embodying the invention in a form which I have found satisfactory includes a blade providing a scrapingedge across which the yarn is drawn, and a movable member having a surface opposed to the scraping edge, resting on the yarn, and holding the yarn in firm contact with the edge, and a surface opposed to one side of the blade and cooperating therewith to confine the particles and fibrous matter detached from the yarn. The movable member is continuously moved, preferably by the travel of the yarn, in such manner that it carries the particles of fibrous matter de 4: tached from the yarn away from the line of travel of the yarn and continuously discharges them from the cleaner.

The invention may best be understood from a detailed description of a specific yarn cleaner embodying it, such as that shown in the accompanying drawing, in which Fig. 1 is a view of the cleaner looking in the direction of the arrow 1 in Fig. 4;

Fig. 2 is a view similar to Fig. 1, but 5%? sectioned on the line 22 of 3;

Fig. 3 is a view of the cleaner looking in the direction of the arrow 3 in Fig. 4; and Fig. 4 is an enlarged transverse section of the cleaner taken on the line 4-4 of of: Fig. 1.

The cleaner illustrated has a supporting plate 10 provided with a bracket 11. in order that the plate 10 may be tipped lat orally at any desired angle to the horizontal, the bracket 11 is provided with a pin 12 projecting at one end of the plate 10 and adjustably secured by means of a set screw 13 in a socket l-i at the outer end of a supporting arm The traveling yarn A to be cleaned is guided across the plate 10 in a longitudinal direction by a front thread guide 16 and a rear thread guide 17. Between these guides is mounted a cleaning unit consisting of fixed member 20 and a rotatable member 30.

The fixed member 20 has the form of a blade projecting perpendicularly outward from the surface of the plate 10. It is secured to the plate by screws 21 passing through tabs 22 at the ends of the blade The front end portion 23 and the rear end portion 24 of the blade are straight. while the middle portion 25 of the blade is arcshaped. The blade 20 is bevelled at 26 on its rear or outersidc so as to provide it with an acute scraping edge 27.

The rotary memberBO is mounted on 21 depending pivot pin 31 which is fixed in a bracket 32 secured to the plate 10. The axis of this pin is slightly nearer the middel por tion 25 of the blade 20 than is the center of phe are on which this portion of the blade The shape of the rotary member is best shown in Fig. 4. Although this member is preferably made of a single piece, it may for convenience in description be regarded as consisting of: a disc 33 having a fiatsurface 34 opposed to the edge 27 of the blade 20; a drum 35 of less diameter than the disc and having a cylindrical surface 36 opposed to the inner or front side 28 of the blade 20; and a sleeve 37 which cooperates with a central hole through the disc and drum in providing the rotary member with a long bearing on the pin 31. The disc 33 has a bevelled surface 38 at the periphery of its fiat surface 34. The drum 35 has a radius less than that of the arc-shaped middle portion of the blade 20, and is spaced a short distance from the central part of the blade, so that the cylindrical surface 36 of the drum and the inner side 28 of the blade 20 enclose two wedge-shaped spaces 40, 42 connected by a narrowpassage 41.

The operation of the cleaner which has been described is as follows :The device is threaded by dropping a yarn A into the re cesses in the front and rear guides 16 and 17. As soon as the pull is applied to the yarn to draw it forward through the cleaner, the yarn is brought against the bevelled edge 26 of the blade and the bevelled edge 38 of the disc 33 and raises the rotary member sufliciently to permit the yarn to enter between the scraping edge 2'7 of the blade 20 and the tint surface 34 of the disc The guides 16, 1'? are so positioned that after the yarn has slipped under the surface 34 it comes in contact with the cylindrical surface 36 of the drum 35 at substantially the same point in its travel as that at which it crosses the scraping edge 27, and is deflected slightly from a straight line of travel at this point so that it contacts firmly with. the cylindrical surface. The flat surface 3 is urged toward the scraping edge 27 by the weight of the rotary member 30 so that the yarn is held in firm contact bot-h with the edge and with this surface.

As the yarn is drawn across the scraping edge 27 in firm contact therewith, the edge serves to scrape from the yarn small particles and impurities of all sorts. Such particles and any fibrous matter scraped off with them are confined in the wedge-shaped space between the cylindrical surface 36 of the drum 35 and the front part of the inner surface 28 of the blade 20. The friction between the yarn and th surfaces 34 and 36 causes a continuous rotation of the member 30. In this rotatiom the portion of the surface in contact with the yarn is continuously moved in a direction approximately longitudinal of the middle portion of the blade 20, and. in this movement. carries aw. y from the yarn any particles and fibrous matter which may become lodged between the surface 34 and the scraping edge 27. The movement of the cylindrical surface 36, in the rotation of the member 30. carries the particles and tibrous matter confined in the wcdgeshapcd space 40 through the narrow passage -21 between the central portion of the blade and the drum 35 so that such mat ter is continuously discharged through the wedge-shaped space 42 between the drum 35 and the rear part 24 of the blade. Any of the particles of fibrous matter which may adhere to the surface 36 are loosened from this surface by a'iixcd scraper whose end 46 is just out of contact with the surface 36. and are, therefore. contimiouslv discharged from the cleaner.

The firmness of the contact of the scraping edge 27 with the yarn and the tension applied to the varn may be regulated by changing the angle of the plate 10 to the horizontal. In this manner the pressure on the yarn is adjusted so that the yarn conthere? e, the invention is not confined to p: .LlCllllll' features of the embodiment showin except so far as is Sp'd'clilml in th claims which follow. liurthermore, certain features of the yarn cleaner described form the subject matter of claims in my copending application filed January 3, 1924-, Serial No. 684L131. and are therefore, not clain'icd in this application.
